Efficiency wise, a CCFL is not as good a modern fluorescent lamp with a high efficiency electronic ballast.

I don’t think that CCFL has been superior to LED backlights for a long time. And that’s not even considering LCDs with RGB LED backlighting, which allow for backlight spectra that closely match the filters on the subpixels.

Hmm, I'm not convinced. I have an LED backlit monitor at home, I can't remember the brand, but it's around 3 years old and the colour rendering is poor, compared to lots of the older CCFL monitors I've used in the past. I do regret buying it and only did so because it seemed like a good price i.e. cheap. The problem is the red is very poor.

You mentioned the reason right there, you bought a cheap monitor and the color rendering is poor. LED backlit monitors with excellent color rendering are widely available but they cost a bit more. I have one that has very good red, the old ccfl monitors look dull in comparison.
The thing about ccfl is that once the phosphors got dialed in there was little savings in trying to cheap out on color rendering, they seem to be more consistent. They're pretty much a thing of the past though, I don't think anyone is still making ccfl lcds.

I've just checked the label. It's an Acer V226HQL. My advice is steer clear. It's crap.
I still don't have the heart to throw it out. Perhaps I should donate it to a charity shop and get a better one?

That's because you bought monitor with bottom of the range WLED backlight. If you spent a bit more, you could get IPS, PLS or VA with decent WLED. If not cheaping out, you can get a LED backlit wide gamut monitor which is better than any with wide gamut CCFL, not to say standard CCFL.
EDIT: actually you just made a stupid choice, at exactly the same price you could get a quite decent IPS monitor of the same size, not TN junk.

I accept I made bad decision, but could I have bought that back in 2016? If so, where?
